Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482212, here are decompositions:

43 + 31482169 = 31482212
109 + 31482103 = 31482212
199 + 31482013 = 31482212
313 + 31481899 = 31482212
499 + 31481713 = 31482212
691 + 31481521 = 31482212
733 + 31481479 = 31482212
739 + 31481473 = 31482212

Showing the first eight; more decompositions exist.
